This publically accesible fixture may be found at a roadside food stall area on the outskirts of Bangkok, Thailand

The cost of using this outdoor facility is 3 Baht (which is roughly equivalent to 10 cents). The fare must be paid to a female attendant, who oversees the use of the open-air facility. She also instructs the customers to flush this concrete fixture with a bowl of water, which is visible in the left part of the photo.
